GRAIN-BINDER.

fiPECIFICATION forming part of Letters Patent No. 317,292, dated May 5,1885.

Application filed January 11, 1884. (No model.)

To aZZ whom it may concern.-

Be it known that I, ROBERT BROWN, a citizen of the United States, and aresident of Springfield, in the county of Clark and State of Ohio, haveinvented certain new and useful Improvements in Grain-Binders, of whichthe following is a specification.

This invention relates to grain-binders; and it consists in certainimprovements upon the machine shown and described in Letters Patent No.266,087, granted me October 17, 1882.

The object of this invention is to retain the same general features ofthe'binding mechanism therein described, with improvements therein forsecuring a better operation of the binding mechanism.

Another feature of my invention is the employment of revolving sectionsof the bindingtable, so as to deliver the bundle in a better manner, thedetails of which will be fully set forth in the description of theaccompanying drawings, in which- Figure 1 is a plan view of thebinder-table, tripping and driving mechanism with the knot-tying devicesremoved. Fig. 2 is a plan view of the binder-table with the tripping andpacking mechanism removed. Fig. 3 is aside view of the combined cam andgear wheel. Fig. 4 is an edge view'of the same. Fig. 5 is a sectionalelevation of the packing-fingers, tripping device, and binder-table.Fig. 6 is a sectional elevation of the tripping-finger and support inposition above the table. Fig. 7 is a detail view of parts of thepackers. Fig. 8 is a section on line 2 2, Fig. 1. Fig. 9 is a section online 00 00, Fig. 8. Fig. 10 is a broken inside elevation of the frameand tripping devices shown in Fig. 8. Fig. 11 is a detail, partly insection, of the tripping mechanism and the combined cam and gear wheel,being taken on the line a," w of Fig. 3. Fig. 12 is a plan View of thetripping crank-arm on line y y, Fig. 11; Fig. 13, a perspective view ofthe combined compressor and ejector fingers. Fig. 14 is a top plan viewof the same. Fig; 15 is a side elevation of the compressor. Fig. 16 isan enlarged view, partly in section, of the compressor and ejectorfingers, their ends being broken off, showing the means for uniting thecompressor and ejector fingers. Fig. 17 is a side elevation of thedriving-gear.

A represents the binder-table,which is suitably supported in the usualmanner.

a a represent beams upon which the binding mechanism is mounted.

B represents the ejector and compressor shaft, upon which is mounted thecompressor and ejector fingers, as shown in my said Patent No. 266,087,October 17, 1882.

O 0 represent revolving sections or leaves of the binder-table,which areprovided with eyes or journal-holes, formed in strengthening-ribs O,which are secured to the under side of the revolving sections or leaves,and through which eyes passes the ejector and compressor shaft B, towhich they are keyed.

12 represents angle-pieces, forming part of revolving sections or leavesO c.

d D represent the ejector and compressor fingers, which are also keyedto said shaft. These fingers are made adjustable, as will be hereinafterdescribed. When the ejector and compressorshaft B is revolved to eject abundle, the sections or leaves 0 0 revolve with the ejector-finger andassist in delivering the bundle, and this is an important feature of myinvention, as it makes a positive delivery of the bundle.

bb represent stationary portions of the binder-table under the knottingmechanism,.between the revolving sections or leaves 0 c.

E E represent the packers,which are driven by the crank-shaft e; and c 0represent links at the heel end of the packers for securing the propermotion of the same, as stated in my said former patent.

G represents a guard secured to the beam a, to hold the grain down onthe table.

The mechanism here shown is designed to be used in connection with theknotting mechanism shown in my said former patent.

Instead of employing the tripping devices as there shown I operate themin the following manner: II represents the combined cam and gear wheelfor driving the binding mechanism, and is provided upon its inner facewith a cam, h, which comes in contact with an arm, I, pivoted to a stud,i, on the end of the bindenframe a, and presses it down on the crank-armI, which is keyed upon the ejector and compressor shaft B, so as to givea slight reverse or inward motion to the sections 0 c bined cam and gearwheel H, and engaging and holding the pins 8 out of engagement with .thesprocket-wheel L, which is rigidly convwheel L, which isrrigidlyconnected to the of the binder-table to compress the grain, and I toslacken the cord around the bundle while the knot is being tied. Inorder to limit the inward movement of the revolving sections or leaves,Iprovide lugs f on the inner face of the stop-motion pinion H, the teethof which engage with the segmental teeth Z on the combined cam and gearwheel H. The stop-motion pinion is on the shaft of the compressor andejector arms, as described in my former patent. The arm I will be caughtby the lugs directly after the backward motion isimparted and arrest it.This engagement is but momentary and only during the act of tying theknot. K represents an inclined lug, formed upon the end of trigger S,which is pivoted to the face of combined cam and gear wheel H, as shownin Figs. 3 and 11, to operate the springclutch,which connects thecombined cam and gear wheel H with the continuouslyoperated drive-wheelZ, the latter being a gear-wheel meshing with a pinion driven by anindependent driving-shaft.

8 represents a clutch-pin pivoted to lever S, projecting throughan'opening in the comwith recesses .9 formed on the inner face of nectedto the drive-wheel Z.

trepresents a spring secured to the inner face of the combined cam andgear wheel H, pressing against the free end of the trigger S, so as tohold the clutch-pin s normally in engagement with continuously-operateddrivewheel Z. The sprocket-wheel L is provided with sprocketteeth fordriving the packershaft 6, a sprocket-wheel, 6 being also on said shaft.

M represents a tripping-shaft journaled to the frame above thebinder-table; m, an arm keyed to said shaft,projecting downward over thetable, as shown in Fig. 5, against which arm the grain is forced by thepackers.

N represents a crank-arm keyed upon the rock-shaft M; O, a rod or linkconnectingarm N with the arm 1?, which is secured to the crankshaft- Q.

R represents a crank-arm projecting from the opposite end of crank-shaftQ, which is journaled upon the frame a in such relation to lug K on thelever S as to bring the free end of arm B into engagement with the outerface of the lever S when the parts are in their normal position orstationary, pressing the free end of lever S and its springt inward,

the recesses s on the face of the sprocketcontinuously-operateddrive-wheel Z.

When a sufficient amount of grain has been forced against the finger m,itlifts said finger, rocks the shaft M, and lifts the arm N and the link0. The link 0 in turn operates the arm 1?, which rocks the crank-shaftQ, and moves the arm R over the face of the inclined lug K, releasingthe lever-trigger S, which, by

wheel H, and brings the arm R back into en-E' 7 5 gagement with thelever S,and withdraws the clutch-bolt 8 out of engagement with thesprocket-wheel L,thereby throwing the binding mechanism out of gearduring the period of collecting grain for the next bundle. The armgnfalls back to its normal position as soon as the tripping is effected.This act of tying the knot and ejecting the bundle is done very quickly.

D (1 represent the combined ejector and compresser finger, made in twoparts, so as to be readily detachable and adjustable, the part dbeingadjusted circumferentially upon the hub D for securing the device to theshaft B by a feather.

0 represents a flange or guard projecting radially up from the hub D.

' V represents a bracket orlug projecting up from near the center of hubD. 12 represents a series of openings or slots pierced through the ledgeof the part V. The metal forming the spaces between these openings issecurely joined to the fiange c, the parts D, hub D, flanges V c, andteeth or openings 1; all being cast in one piece. These flanges V and oare sufficiently far apart to form an opening sufficiently large toreceive the projecting hook j of finger d.

J" represents a' semicircular recess in the endlof finger d,whichencircles hub D, as shown in Figs. 13 and 16, there being a sufficientspace between the parts J and the hub D to allow the teat or lug cl topass under the ledge or teeth and to engage therewith by alateralmovement of the part (I, as shown in Fig. 16. The object of theseseveral spaces between the teeth or spaces 12 is to allow the lug d tobe changed from one space to the other, so as to adjust the finger dreadily on the shaft B and to the finger D."

u represents a spring attached to finger d, with its forward end bent toform an arm which presses against the ends of teeth 12, so as to holdthe finger d in the position shown in Fig. 16.

\Vhen it is desired to remove the finger d, it is pressed down so thatthe groove J bears against the hub D, releasing the lug d fromengagement with the teeth or openings 0, when adjusted without the useof nuts and bolts or I set-screws, which is of material advantage in thesetting of the compressor and ejector fingers to suit the differentkinds of grain to be bound.

Having thus described my invention, what I claim is- 1. The combinationof the stationary binding-table, having one or more movable fiatsections or leaves forming part of the flat table-surface, with therevolving compressor and ejector shaft B, having the movable sections orleaves secured thereto so as to revolve with said shaft, substantiallyas herein set forth.

2. In combination with the shaft B and one or more movable sections orleaves of the binder-table revolving therewith, the arms I I and flange71, arranged to give an inward movement to the shaft B and movablesections of the table to compress the bundle for tying, substantially asdescribed.

3. In a grain-binder, the combination of the tripping-finger m, shaft M,cranks and links N O P Q R, spring tripping-bolt S,continuously-operating drive-wheel Z, and sprocketwheel provided withrecesses s, substantially as specified.

4:. In a grain-binder, the combination of the revolving shaft B, and themovable sections or leaves 0 c, and the ejector-finger D, secured uponsaid shaft and revolving therewith, with the stationary binder-tablehaving openings in which the movable sections or leaves operate,substantially as herein set forth.

5. In a grain-binder, the binder-table composed of the stationaryportions a, and movable sections 0 c, and the stationary portions 12,arranged between the sections 0 c, substantially as specified.

6. The combination of the compressor and ejector shaft B, having the armI and stopmotion pinion H, provided with lugs f, and the pivoted arm I,mounted upon the binderframe, with the combined cam and gear wheelhaving segmental teeth Z, substantially as set 4 5 forth.

In testimony whereof I have hereunto set my hand.
